To merge the several trajectories of satellites into the one, select several objects in the «Manager of objects» window and press the «Merge objects» button.
Next, you will be prompted to select a file with TLE-records of the investigated object for the initial approximation. Close this window or press «Cancel» button, if there is no such file.
Wait for completion of the RMS calculation of a new merged trajectory and decide whether to create it as a new object or not.
After confirming the creation of a new trajectory (object), it will be created and available in the «Manager of objects» window for the further analysis and report generating.
